74 year old (in 2019) former research chemist with no musical training. I have three relatively unused mandolins acquired about 12 years ago (1924 Gibson A-style, Weber Y2K4, and a Trinity Octave), two ukuleles (Mitchell MU100CE koa-wood concert and Breedlove Pursuit concert in myrtle-wood) purchased in early 2019. Dulcimers: (1) a kit-made Folkcraft solid walnut hourglass, 27" VSL, 2-1/8" deep body, with rich brilliant sound. I purchased this in May 2019 on eBay from the guy who assembled it (a first timer), but corrected some errors he had made, then did some modifications to improve its sound and playability; (2) a personally assembled (in June 2019) 46-year old 1973 Black Mountain hourglass kit having a cherry body and spruce top with 25-3/4 inch VSL and 1-7/8" thick body with a warmer sound. Its assembly presented some problems due to age and slight distortion of components, but those were resolved during assembly. Also made modifications to improve appearance, sound, and playability. Both are mounted with D'Addario strings. Wife has a 1988 teardrop Folkcraft dulcimer purchased in March 2019.
